description

These quadruple differential comparators are

fabricated using LinCMOS technology and

consist of four independent voltage comparators

designed to operate from a single power supply.

Operation from dual supplies is also possible if the

difference between the two supplies is 2 V to 18 V.

Each device features extremely high input

impedance (typically greater than 10

Ω),

allowing direct interfacing with high-impedance

sources. The outputs are n-channel open-drain

configurations and can be connected to achieve

positive-logic wired-AND relationships.

The TLC374 has internal electrostatic discharge (ESD) protection circuits and has been classified with a 1000-V

ESD rating using human body model testing. However, care should be exercised in handling this device as

exposure to ESD may result in degradation of the device parametric performance.

The TLC374C is characterized for operation from 0°C to 70°C. The TLC374I is characterized for operation from

–40° to 85°C. The TLC374M is characterized for operation over full military temperature range of

–55°C to 125°C. The TLC374Q is characterized for operation from –40°C to 125°C.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.

TLC374, TLC374Q, TLC374Y LinCMOS QUADRUPLE DIFFERENTIAL COMPARATORS SLCS118C – NOVEMBER 1983 – REVISED MARCH 1999 PARAMETER MEASUREMENT INFORMATION The digital output stage of the TLC374 can be damaged if it is held in the linear region of the transfer curve. Conventional operational amplifier/comparator testing incorporates the use of a servo loop that is designed to force the device output to a level within this linear region.

TLC374, TLC374Q, TLC374Y LinCMOS QUADRUPLE DIFFERENTIAL COMPARATORS SLCS118C – NOVEMBER 1983 – REVISED MARCH 1999 PARAMETER MEASUREMENT INFORMATION Figure 2 illustrates a practical circuit for direct dc measurement of input offset voltage that does not bias the comparator into the linear region. The circuit consists of a switching-mode servo loop in which U1a generates a triangular waveform of approximately 20-mV amplitude. U1b acts as a buffer with C2 and R4 removing any residual dc offset.

TLC374, TLC374Q, TLC374Y LinCMOS QUADRUPLE DIFFERENTIAL COMPARATORS SLCS118C – NOVEMBER 1983 – REVISED MARCH 1999 PARAMETER MEASUREMENT INFORMATION Response time is defined as the interval between the application of an input step function and the instant when the output reaches 50% of its maximum value. Response time, low-to-high-level output, is measured from the trailing edge of the input pulse. Response-time measurement at low input signal levels can be greatly affected by the input offset voltage.
